One piece!

I really like the idea of this item being one piece. There are no seams to fail! The instructions were very good and once the old gasket was removed, installation was easy.

lost shipping

after 3 weeks 2 seals showed up and with rain happening I needed to seal it so I purchased from another supplier and received it in 2 days. and sealed it way before both of yours showed up. Then your refund was less shipping cost. Surprise.
Not a good time.
Thank you,

Good product. Thicker than original

Great rubber product, as advertised. Would recommend to others. OEM part on my AC was difficult to remove, not as easy as depicted in video. (The video makes the job look routine simple. The process is a wee bit more involved. ) Had to remove old one with a lot of scraping, rubbing, etc. using a solvent (be careful with solvent on the TPO roof!). ...Read More

This product easily applied to cleaned area of AC unit. The Steele product was thicker than the original part, but bolts holding AC to roof are long enough to cover the difference when tightening down. Is an involved job that can be a DIY project if you are okay with being on the RV roof, rolling an AC, and doing basic assembly work. Not something you would want to do on a summer afternoon.
